ORIF – Open Reduction Internal Fixation

What is ORIF Surgery?

An open reduction internal fixation (ORIF) refers to a surgical procedure to fix a severe bone fracture, or break. “Open reduction” means surgery is needed to realign the bone fracture into the normal position. “Internal fixation” refers to the steel rods, screws, or plates […]

A Patient’s Guide to the Biceps Tendon

Biceps Tendon

Biceps Tendon

Key Points

The long head of the biceps (LHB) originates at and around the supraglenoid tubercle. Although it is intra-articular, it is extrasynovial. Although acute ruptures of the LHB do occur, LHB ruptures are more commonly the result of chronic biceps tendonitis. There is such a close association between subacromial impingement and […]

Open Capsular Release for Adhesive Capsulitis

Open surgical release of the glenohumeral capsule was more commonly utilized to treat patients with severe and refractory adhesive capsulitis prior to the advancement of arthroscopic techniques to treat this difficult patient population. Although the peri-operative morbidity of this open approach to treatment is now accepted to be somewhat greater than its arthroscopic counterpart, use […]

Arthroscopic Capsular Release for Adhesive Capsulitis

Because adhesive capsulitis of the shoulder, by definition, is due only to a tight and thickened glenohumeral capsule, arthroscopic surgery seems ideal for the treatment of this problem. The capsule is best viewed, and more directly surgically addressed, by an intra-articular approach rather than an extra-articular, open surgical approach. Arthroscopy allows circumferential capsular release as […]

Nonsurgical Treatment for Adhesive Capsulitis

Nonoperative treatment commonly begins with measures to reduce shoulder pain and inflammation including topical treatments of heat, ice, transcutaneous electric stimulation, transcutaneous salves and balms, acupuncture, massage and systemic medications [nonsteriodal anti-inflammatory drug (NSAID) class medicines and oral corticosteroids]. The relative contribution to recovery that any of these treatment measures provide remains unclear and their […]

Physical Findings of Adhesive Capsulitis

The physical examination of patients with adhesive capsulitis reveals a global reduction in range of motion with a marked decrease in glenohumeral translation also present. Examination of the opposite shoulder (if normal) is performed to identify the patient’s expected normal range of motion for comparison. Evaluation for limitation of pure glenohumeral motion (best measured in […]

Clinical History and Classification of Adhesive capsulitis

Adhesive capsulitis is a disease that typically progresses through three clinical phases. Patients with this condition will have varying clinical complaints depending upon the phase they are experiencing at the time of interview. The initial inflammatory “painful” phase begins with a spontaneous onset of aching discomfort at rest and the development of pain with use. […]

Anatomy and Biomechanics of the Glenohumeral Capsule

The shoulder is an inherently loose articulation permitting a wide range of motion. The glenohumeral capsule remains lax throughout mid-range motion where stability is conferred by the dynamic action of the rotator cuff and the conforming articulation of the humeral head and the glenolabral surface. The capsuloligamentous structures about the glenohumeral joint act as passive […]

Complications and Special Considerations

Fracture of the proximal humerus presents a therapeutic challenge. Numerous complications have been reported. Most common complications include AVN, malunion, neurovascular injury, and adhesive capsulitis (frozen shoulder). Hardware failure, infection, and nonunion are less common.

AVN is a common complication following three- and four-part fractures. The incidence of AVN of the humeral head ranges from […]

Clinical Evaluation

The most common mechanism for sustaining a pectoralis muscle injury is from weight-lifting or athletics. Wolfe et al.It described the transition period from eccentric loading to concentric loading (bench press position) as the most stressful to the inferior muscle fibers of the pectoralis muscle. The patient typically presents after sudden onset of pain in the […]
